This disc reproducing apparatus is disclosed in Japanese Patent Application Laid-Open No. 8-167222.

[0004]

However, since the distance between the disks arranged in the disk rack is short, the lifter rises to select the disk and guide it with the guide rollers. You need to stop exactly at the disk location. Therefore, the precision of the position control of the transport unit must be improved, and there is a problem that it takes time to control the transport unit to stop accurately at the selected disk position.

FIG. 8 is a schematic configuration diagram when a partition plate of a disk rack is inclined. As shown in FIG. 8, the partition plate 3a of the disk rack 3 may be tilted due to a variation in dimensional accuracy of the partition plate 3a. When the disk 4n1 is stored in the tilted partition plate 3a, the disk is stored. Since the disc 4n1 is inclined, when the disc 4n1 is pushed up by the lifter 502, the disc 4n1 is pushed up by being inclined along the partition plate 3a. Was.

FIG. 9 is a schematic configuration diagram when the positioning accuracy of the transport unit is poor. As shown in FIG. 9, when the accuracy of the position control of the transport unit is poor, the lifter 502 may stop between the selected disk 4n1 and the adjacent disk 4n2. In such a case, either of the disks cannot be lifted by the lifter 502 or both disks may be lifted. In either case, the disks cannot be guided by the guide rollers 509, and the disks are transported to the transport unit. A problem arises that cannot be performed.

When a disk is stored in a disk rack and a charged disk is selected and pushed up by a lifter, the adjacent disks are attracted by static electricity,
It may pop up with the selected disc.

Then, the sucked disk is moved by the guide roller together with the selected disk. When the selected disk is transported to the transport section, there is no guide for the sucked disk. There has been a problem that the sucked disk falls from the disk rack, making the transport unit inoperable and damaging the dropped disk.

SUMMARY OF THE INVENTION It is an object of the present invention to reliably transfer only a selected disk when transferring a selected disk from a disk rack to a transfer unit. It is another object of the present invention to provide a disk reproducing apparatus in which a transport unit stops at a selected disk position and shortens a transport time required to transport a disk from a disk rack to a transport unit.

[0010]

According to a first aspect of the present invention, there is provided a disk rack having a partition for accommodating a plurality of disks arranged in a horizontal position in a vertical position. A disk reproducing device comprising: a disk reproducing unit that reproduces a disk; and a transport unit that mounts a disk selected from the disk rack on the reproducing unit and that is movable along an arrangement direction of the disks housed in the disk rack. Wherein the transport unit has a lifter portion which extends from the transport portion to swing freely and pushes up the disk from the lower surface of the disk rack, and the lifter portion pushes up both the selected disk and the disk adjacent to the selected disk. A contact surface having a length substantially equal to the interval between the partition plates; and a contact surface adjacent to both sides of the contact surface. It is characterized by comprising an inclined surface forming a V groove to push up the disc that.

According to a second aspect of the present invention, there is provided the disk reproducing apparatus according to the first aspect, wherein the contact surface has a recess in which the selected disk is substantially upright. Features.

According to a third aspect of the present invention, in the disk reproducing apparatus according to the first or second aspect, the inclined surface forming the V-groove is a step from the contact surface. Is provided at a lowered position.

Therefore, when the lifter unit pushes up both the selected disk and the disk adjacent to the selected disk, the adjacent disk is pushed up by being guided by the V-groove, and the space between the selected disk and the selected disk increases. The selected disk can be easily taken out.

Further, since the contact surface for pushing up the selected disk has a length substantially equal to the interval between the partition plates of the disk rack, the selected disk can be positioned even if the stop position of the transport unit is not precisely positioned. Can be pushed up. Therefore, since the positioning accuracy of the stop position of the transport unit does not need to be improved, the time until the transport unit stops can be reduced.

A disc loader 11 for mounting the disc 4n on the turntable 10 of the disc reproducing section 9 arranged along the rail 8 is rotated in the transport section 5 about the shaft 5a of the transport section 5. It is attached.

The operation of the transport unit 5 for transporting the disk 4n to the turntable 10 will be described. FIG.
Is a cross-sectional view for explaining the operation of transporting the disk 4n to the turntable 10. FIG. In FIG. 2, the transport unit 5 is movable in the directions of arrows E and F along the rail 8, and a means (not shown) for indicating an address corresponding to the disk 4 n provided on the disk rack 3 is provided on the transport unit 5. Control means (not shown) controls the disk drive 3 to move to a predetermined storage position of the disk rack 3 storing the specified disk 4n by the address reading means (not shown).

The designated disk 4n stored in the disk rack 3 is pushed up from below the disk rack 3 by a lifter, which will be described later, provided in the transport unit 5, and the upper outer periphery of the pushed up disk 4n is guided by guide rollers. While moving to the disk loader 11 in the vertical position.

FIG. 3 is a schematic structural view of the transport unit when the lifter unit is not raised. In FIG. 3, a transport unit 5 is provided so as to surround three sides of the disk rack 3 accommodating the disk 4n. Below the disk rack 3, the transport unit 5 is interlocked with a lifter arm 501 that swingably extends from the transport unit 5. There is a lifter 502.

The lifter arm 501 has a swing fulcrum 50
3 and a contact portion 505 for rotating the lifter 502 at an end opposite to the lifter 502 via the swing fulcrum 503.
There is. The lifter section 504 is provided in the transport section 5 and moves in the up-down direction and is connected to an upper end of a spring 5.

FIG. 4 is a schematic structural view of the transport section when the lifter section is raised. In FIG. 4, when the lifter unit 504 moves downward against the urging force of the spring 506 by a driving force from a driving unit (not shown), the contact unit 505 of the lifter arm 501 moves downward, and the lifter arm 501 moves. Swings up the lifter 502 linked to.

When the lifter 502 swings upward, the disk 4n stored in the disk rack 3 is pushed up from below the disk rack 3. The pushed up disk 4n moves to the disk loader 11, which is in the vertical position, while being guided by the guide roller 509 extending from the transport section 5 on the upper periphery of the disk 4n.

FIG. 5 is a schematic structural view of a drive unit in which the lifter unit 504 moves up and down. In FIG. 5, a lifter rack 510 is provided in the lifter section 504. Then, by the motor 511 attached to the transport unit 5,
The driving force of the motor 511 is transmitted to the transmission means 512, and the lifter rack 510 meshing with the transmission means 512 moves in the vertical direction.

FIG. 6 is a schematic configuration diagram showing the state of the lifter 502, the guide rollers 509, and the disk when a disk is selected. In FIG. 6, the lifter 502
Has a contact portion 12 formed at a portion in contact with the outer peripheral portion of the disk 4n. The contact portion 12 has a contact surface 13 having a length substantially equal to the interval between the adjacent partition plates 3a, and a contact surface 1
Inclined surface 15 and inclined surface 1 forming V-grooves 14 on both sides of 3

The inclined surface 15 has a length capable of pushing up the disk 4n2 adjacent to the selected disk 4n1. Then, when the lifter 502 rises, the outer peripheral portion of the adjacent disk 4n2 slides down the inclined surface 15 and is guided by the V groove 14.

Since the V-grooves 14 are on both sides in the vicinity of the contact surface 13, the outer peripheral portion of the adjacent disk 4n2 that contacts the V-groove 14 approaches the selected disk 4n1. V groove 14
Of the inclined surface 16 is gentle, so that the adjacent disks 4n2 incline in the direction away from the selected disk 4n1 and contact the partition plate 3a in accordance with the inclination of the inclined surface 16.

The guide roller 509 has a length that can guide the outer periphery of the upper end of the selected disk 4n1 even if the selected disk 4n1 is inclined when the selected disk 4n1 is pushed up by the lifter 502. However, the adjacent disk 4n2 is
Is inclined in a direction away from the guide roller 50.
Thus, only the selected disk 4n1 can be guided and moved by the guide roller 509.

Since the contact surface 13 for pushing up the selected disk 4n1 has a length substantially equal to the interval between the adjacent partition plates 3a, the stop position of the transport unit 5 does not need to be positioned with high precision. The selected disk 4n1 can be pushed up by the lifter 502.

When the selected disk 4n1 is pushed up by the lifter 502, the adjacent disk 4n2
Is pushed up with an inclination in a direction away from the selected disk 4n1.
Even if is charged with static electricity, it does not stick to the selected disc 4n1 due to the static electricity, and does not move along with the selected disc 4n1 by the guide roller 509.

Another embodiment of the disk reproducing apparatus according to the present invention will be described with reference to the schematic diagram of FIG. FIG. 7 shows the lifter 502a and the guide roller 50 when a disc is selected.
FIG. 9 is a schematic configuration diagram showing states of a disk 9 and a disk. In FIG. 7, the lifter 502a has a contact portion 12a formed at a portion in contact with the outer peripheral portion of the disk 4n.

The contact portion 12a has a length substantially equal to the distance between adjacent partition plates 3a, and has a contact surface 13a provided with a concave portion 17 for supporting the selected disk 4n1 substantially upright.
Inclined surface 15 and inclined surface 16 in which step 18 is provided on both sides of contact surface 13a to form V-groove 14 at a position lower than recess 17
Having.

The interval between the recesses 17 is determined by the selected disc 4n.
When the selected disk 4n1 enters the concave portion 17, the selected disk 4n1 is substantially upright by the concave portion 17.

The step 18 pushes up the disk 4n2 adjacent to the selected disk 4n1 and pushes the guide roller 50
When guiding the disk 4n1 selected at 9, even if the adjacent disk 4n2 is inclined toward the selected disk 4n1, the guide roller 509 has a length that does not make contact.

The inclined surface 15 and the inclined surface 16 which are provided with a step 18 on both sides of the contact surface 13a and form the V-groove 14 at a position lower than the concave portion 17 are the same as those in the above-described embodiment, and therefore the description thereof will be omitted.

According to this embodiment, the adjacent disks 4n
2 is located lower than the selected disk 4n1 and does not contact the guide roller 509, and the selected disk 4n1 is almost upright by the concave portion 17, so that the selected disk 4n1 can be guided reliably.

Since the selected disk 4n1 stands almost upright, it does not come into contact with the partition plate 3a when moving to the transport section while being guided by the guide rollers 509.
Contact scratches on the disk surface of the selected disk 4n1 are eliminated.

[0037]

According to the present invention, the selected disk and the disk adjacent to the selected disk are pushed up together,
Adjacent disks have a lifter shape that is inclined in the direction in which the distance from the selected disk increases, so that the selected disk can be easily taken out. Also, since the contact surface of the lifter that pushes up the selected disk has a length substantially equal to the interval between the partition plates of the disk rack,
The selected disk can be pushed up without having to position the stop position of the transport unit with high accuracy. Therefore, the positioning accuracy of the stop position of the transport unit does not need to be improved, and the time until the transport unit stops can be reduced.
